METHOD OF MANUFACTURING GRAPHITE BODIES

Patent ·
OSTI ID:4098131
Graphite bodies having a density of 1.90 to 1.98 are manufactured by grinding very pure synthetic graphite until all particles have a diameter of below 40 - and 80% have a diameter below 20 - and then cold compacting the powder under a pressure of 3150 to 11,025 kg/cm/sup 2/. Highdensity dispersion fuel elements can be manufactured by incorporating up to 50 vol.% fissile or fertile material in the graphite powder; thus a compacted mixture containing 0.3 vol.% uranium and 0.6 vol.% thorium has a density of 2.4 at least.
